Hi!
Thank you kindly for your comments. I get and appreciate your point. This is also my observation that sometimes we deal with misunderstanding and misusing of methods in computational neuroscience. Nevertheless, I could see a significant amount of publications, even in reputable journals applying the 3dClustSim for thresholding cross-platform. I wonder, why should it necessarily be bad, if it is done correctly. I have to admit, I find the 3dClustSim approach to thresholding very elegant.
Best wishes
